  • Is there some fundamental reason this process can't be automated? Back around 1990 I was updating some process control equipment with modern servo drivers and they had a set up function that used a (hot buzz word of the day) fuzzy logic controller to set up PID values. I'm not a programmer so of course something like that seems like it would be simple to me to apply. :-) Then there wouldn't be so much trial and error when configuring for a new air frame or motor/prop combination.
  • Thank you for your replies Tom
  • usually the values for pitch and roll are the same
